Claim JTAG device.
Syntax
jtag claim <mask>Set claim mask for current JTAG device.
DESCRIPTION- This command attempts to set the claim mask for the
current JTAG device. If any set bits in <mask>
are already set in the claim mask then this command returns error-
"already claimed".The claim mask allow clients to negotiate control over JTAG devices. This is different from jtag lock in that 1) it is specific to a device in the scan chain, and 2) any clients can perform JTAG operations while the claim is in effect.
Note(s)
- Currently claim is used to disable the hw_server debugger from controlling microprocessors on Arm DAP devices and FPGA devices containing MicroBlaze processors.
Returns
Nothing.
